Details: Understanding how interest is calculated helps you make informed decisions about paying down credit card debt and comparing card offers.
Tips: Enter your current credit card balance and the card's APR. The calculator will show your estimated monthly interest charge if you don't pay the balance.
Q1: Is interest charged if I pay my balance in full?
A: No, most credit cards offer a grace period when you pay your statement balance in full by the due date.
Q2: How can I reduce my interest charges?
A: Pay more than the minimum payment, pay early in the billing cycle, or transfer balances to a lower-rate card.
Q3: Why is my actual interest sometimes different?
